查詢TABLE中TRIGGER和移除

原本要使用MariaDB內建函式來產生UUID，後來覺得不妥，所以要移除

=====================================================

REATE TABLE USER(
USER_ID CHAR(36) NOT NULL DEFAULT 0,
EMAIL VARCHAR(100) NOT NULL UNIQUE,
PWD VARCHAR(200),
NAME VARCHAR(30),
NICK_NAME VARCHAR(50),
SEX CHAR(1),
HEIGHT DECIMAL(5,1),
WEIGHT DECIMAL(5,1),
BIRTHDAY DATE,
AGE INT,
HOME_PHONE VARCHAR(30),
MOBILE VARCHAR(30),
EMAIL2 VARCHAR(100) NOT NULL DEFAULT '',
PERSONAL_KEY VARCHAR(100) NOT NULL,
PRIMARY KEY (USER_ID)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;





CREATE TRIGGER TRIG_USER
  BEFORE INSERT ON USER
  FOR EACH ROW
  SET new.USER_ID = uuid();


==================================================



查詢TABLE中的TRIGGER

SHOW TRIGGERS LIKE 'USER';




移除TRIGGER

DROP TRIGGER IF EXISTS USER;

設定mariadb server 建立資料庫時預設使用utf8mb4格式

修改 /etc/mysql/my.cnf

sudo vim /etc/mysql/my.cnf

在[mysqld]中加上此行

=============================

[mysqld]

character-set-server=utf8mb4

collation-server=utf8mb4_general_ci

 =============================
